In TimToebrock/Project_Apriori: Implementation of the Apriori Algorithm

Description

Takes a object of class Matrix, ngCMatrix, ngTMatrix, transactions or itemsets and return a corresponding object of class FIMatrix. The rows should represent the itemset and be named. The columns should describe the itemsets. It should be a binary matrix.

Usage

makeFIMatrix(input, support, dataset)

Arguments

input	Object of class matrix, sparse matrix, transactions (arules class) or itemsets containing the frequent itemsets.
support	The support values for the provided itemsets. Should have a length corresponding to the columns of the supplied matrix. If no support is provided it has to be recalculated.
dataset	Either this has to be provided or support. Please provide the initial datasets based on which the frequent itemsets from input with minimal support where calculated.

Value
